Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Participating in Fig. 1～4, this utility model provides a kind of novel wheelset profile dip stick, is the base at existing 4th kind of detector
The wheelset profile dip stick improved on plinth.This wheelset profile dip stick includes main scale 1, flange height dip stick 31 and wheel rim
Width measuring scale 43.Wherein main scale 1 is to be made up of mutually perpendicular horizon rule 12 and miter square 11.Flange height dip stick 31
Being located on horizon rule 12 by chi frame 32, chi frame 32 is positioned at horizon rule 12 and the crossing side of miter square 11, on chi frame 32
Being provided with chute 33, flange height dip stick 31 is installed on chute 33 and can be along chute 33 in the side being perpendicular to horizon rule 12
To sliding up and down.Rim width dip stick 43 is located on horizon rule 12 by chi frame 41, and chi frame 41 is provided with chute 42, wheel
Edge width measuring scale 43 is installed on chute 42 and can be parallel to the direction slide anteroposterior of horizon rule 12 along chute 42.Hang down
Ruler 11 is provided with measurement datum 14, wheelset profile dip stick of the present utility model compared to existing 4th kind of detector,
Improve at the measurement datum 14 of miter square 11.Wheelset profile dip stick of the present utility model also sets on miter square 11
Having measurement adjustment face 13, it is internal to miter square 11 away from the part of horizon rule 12 by measurement datum 14 that this measurement adjusts face 13
Depression is formed, and i.e. measures adjustment face 13 relative to measurement datum 14 to miter square 11 inner recess, and the two is positioned at vertically
The same side of chi 11.In position, measurement datum 14 is positioned on miter square 11 position near horizon rule 12, and surveys
Amount adjustment face 13 is positioned at the position on miter square 11 away from horizon rule 12.See Fig. 1 and Fig. 4, wherein Fig. 1 at dotted line is
Wheel is to partial schematic diagram, and in Fig. 4, being diagrammatically only by property draws instrumentation plan.Wheelset profile dip stick of the present utility model is used for surveying
Amount wheel be not substantially flat wheel to inner side to size time, such as when measuring low-floor tramcar wheelset profile, it measures base
Inner side plane can be fitted tightly by quasi-face 14 with wheel, utilizes it to measure adjustment face 13, can avoid the inclined-plane of wheel rim 5 and convex
Platform 7, utilizes rim width dip stick 43 and flange height dip stick 31 can measure corresponding parameter.
As further improving, it is additionally provided with wheel footpath measuring mechanism.This takes turns the wheel footpath that footpath measuring mechanism includes being located on miter square 11
Graduation mark 25, for reading the measured value that records, also include being located at measure place, adjustment face 13 miter square 11 part can edge
